Description

Technical Field

[0001] This utility model relates to the technical field of roll cleaning equipment, specifically to a device for removing contaminants from the surface of printing plate rolls. Background Technology

[0002] Printing plate rolls are a type of material used in the printing industry. They typically consist of a continuous flexible substrate and a photosensitive coating. This coating allows images to be exposed and, through a series of chemical processes, forms the printed pattern. Printing plate rolls are widely used in gravure printing, flexographic printing, and offset printing. Before use, printing plate rolls usually need to be cleaned and pre-treated to ensure printing quality and avoid contamination.

[0003] Since printing plate rolls are often transported and stored in a rewound state, their surfaces may be contaminated with dust, ink, and other stains. These stains can cause defects in printed materials. Existing cleaning devices often clean only a single surface of the printing plate roll. However, after the cleaned roll is rewound, its cleaned surface will still come into contact with the uncleaned surface of the roll that is subsequently rewound, which often causes secondary contamination to the printing plate roll.

[0004] In view of this, a device for cleaning the surface of printing plate rolls is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problem of secondary pollution that may occur when cleaning printing plate rolls on one side, and to provide a device for cleaning the surface of printing plate rolls.

[0007] Furthermore, the cleaning unit includes a frame and multiple cleaning rollers rotatably mounted on the frame. Gears are fixedly mounted on the side of the multiple cleaning rollers away from the mounting plate. The multiple gears are meshed with the same toothed belt. A connecting rod is fixedly mounted on the gear near the feeding component. A cover plate is fixedly mounted on the frame. A second motor is fixedly mounted on the cover plate. The output end of the second motor is fixedly connected to the connecting rod. The second motor is used to drive the cleaning rollers to rotate when rotating.

[0008] Furthermore, the adjusting component includes a fixed sleeve fixedly installed on one side of the lower frame and a slide rod fixedly installed on the fixed sleeve. The slide rod is slidably provided with a slide sleeve, and the slide sleeve is fixedly connected to one side of the upper frame.

[0009] Furthermore, the adjusting component also includes a slider fixedly installed on the side of the upper frame away from the slide rod, and the mounting plate has a groove adapted to the size of the slide sleeve.

[0010] Furthermore, a screw is rotatably installed inside the slide groove, and a threaded sleeve is threaded onto the screw, the threaded sleeve being rotatably connected to the slider.

[0011] Furthermore, the mounting plate is provided with a third motor for driving the screw to rotate.

[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Please see Figure 1-6 .

[0029] This utility model relates to a surface cleaning device for printing plate rolls, comprising a conveying component 1, which includes a feeding component 11 and a receiving component 12. The feeding component 11 includes a feeding rack 111 and a feeding roller 112 rotatably mounted on the feeding rack 111. The receiving component 12 includes a winding rack 121 and a winding roller 122 rotatably mounted on the winding rack 121. A first motor 123 for driving the winding roller 122 to rotate is mounted on the winding rack 121. A cleaning component 2 is provided between the feeding component 11 and the receiving component 12. The cleaning component 2 includes a bracket 21 and a mounting plate 34 fixed on the bracket 21. A cleaning unit 22 is fixedly mounted on the bottom of the mounting plate 34, and another cleaning unit 22 is slidably mounted on the top of the mounting plate 34. An adjusting component 3 for adjusting the distance between the two cleaning units 22 is provided on the top cleaning unit 22.

[0030] In other words, the conveying component 1 is used to transfer the printing plate roll from the feeding component 11 to the receiving component 12, and during the transfer process, it passes through the cleaning component 2 to complete the cleaning of the printing plate roll. There are two cleaning units 22. The bottom cleaning unit 22 is fixed to the mounting plate 34, and the upper cleaning unit 22 is slidably set to the mounting plate 34.

[0031] Specifically, the cleaning unit 22 includes a frame 221 and multiple cleaning rollers 222 rotatably mounted on the frame 221. Gears 223 are fixedly mounted on the side of the multiple cleaning rollers 222 away from the mounting plate 34. The multiple gears 223 are meshed with the same toothed belt 226. A connecting rod 224 is fixedly mounted on the gear 223 near the feeding component 11. A cover plate 227 is fixedly mounted on the frame 221. A second motor 225 is fixedly mounted on the cover plate 227. The output end of the second motor 225 is fixedly connected to the connecting rod 224. The second motor 225 is used to drive the cleaning rollers 222 to rotate when rotating.

[0032] like Figure 3 The toothed belt 226 is meshed with multiple gears 223, so that when one gear 223 rotates under the drive of the second motor 225, it can drive the other gears 223 meshing with the toothed belt 226 to rotate, that is, to make the multiple cleaning rollers 222 rotate synchronously.

[0033] It should be noted that, in the specific setup, the two second motors 225 rotate in opposite directions, so that the cleaning direction of the bottom of the upper cleaning unit 22 and the top of the lower cleaning unit 22 is the same. This setup is to avoid damage to the printing plate roll.

[0034] In addition, the adjusting component 3 includes a fixing sleeve 33 fixedly installed on one side of the lower frame 221 and a slide rod 31 fixedly installed on the fixing sleeve 33. A sliding sleeve 32 is slidably disposed on the slide rod 31, and the sliding sleeve 32 is fixedly connected to one side of the upper frame 221. The sliding sleeve 32 and the slide rod 31 are used to ensure that the cleaning unit 22 above remains stable when sliding.

[0035] Furthermore, the adjusting component 3 also includes a slider 35 fixedly installed on the side of the upper frame 221 away from the slide rod 31. The mounting plate 34 has a groove 36 that matches the size of the slide sleeve 32. A screw 38 is rotatably installed in the groove 36. A screw sleeve 37 is threadedly connected to the screw 38. The screw sleeve 37 is rotatably connected to the slider 35. A third motor 39 for driving the screw 38 to rotate is provided on the mounting plate 34.

[0036] like Figure 5 and Figure 6 The outer side of the screw sleeve 37 is provided with a T-shaped rotating ring. This rotating ring is used to rotatably connect the screw sleeve 37 and the slider 35. That is, when the third motor 39 starts and drives the screw 38 to rotate, the screw sleeve 37 rotates helically along the screw 38. Because the screw sleeve 37 and the slider 35 are rotatably connected, the slider 35 will move linearly along the axial direction of the screw 38. This realizes the vertical movement of the slider 35 and the upper cleaning unit controlled by the third motor 39. The adjustable setting of the upper cleaning unit 22 not only allows the device to adapt to more sizes of printing plate rolls, but also allows the cleaning intensity of the upper cleaning unit 22 to be adjusted by adjusting the downward pressure distance of the cleaning unit 22, enabling the device to be adjusted and controlled more precisely.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
